Is there current any benefit to having rooms large or multiple rooms; or any future plans?
I tried a couple of games making large room (8×8 and larger) and any effects are difficult to notice. A large ritual room got me lots of succubii, doppledagers and ghosts but an equally large dorm didn't seem to get me more orcs, goblins and ogres.
Manufactories also seem to fair just as well large or small with the same amount of workers assigned.
